  • How to Install Incompatible Android Apps from Google Play

    - by Chris Hoffman
    Some Android apps on Google Play claim to be incompatible with various devices. There’s a good chance that these apps will run fine on many of these devices – you can bypass this check with root access. Some apps won’t actually work after you install them, but many will. This also solves problems with games that will install but refuse to play – for example, Gameloft games with the “this device is incompatible” message.

  • Read only array, deep copy or retrieve copies one by one? (Performance and Memory)

    - by Arthur Wulf White
    In a garbage collection based system, what is the most effective way to handle a read only array if such a structure does not exist natively in the language. Is it better to return a copy of an array or allow other classes to retrieve copies of the objects stored in the array one by one? @JustinSkiles: It is not very broad. It is performance related and can actually be answered specifically for two general cases. You only need very few items: in this situation it's more effective to retrieve copies of the objects one by one. You wish to iterate over 30% or more objects. In this cases it is superior to retrieve all the array at once. This saves on functions calls. Function calls are very expansive when compared to reading directly from an array. A good specific answer could include performance, reading from an array and reading indirectly through a function. It is a simple performance related question.

  • Elmah

    - by csharp-source.net
    LMAH (Error Logging Modules and Handlers) is an application-wide error logging facility that is completely pluggable. It can be dynamically added to a running ASP.NET web application, or even all ASP.NET web applications on a machine, without any need for re-compilation or re-deployment. Once ELMAH has been dropped into a running web application and configured appropriately, you get the following facilities without changing a single line of your code: * Logging of nearly all unhandled exceptions. * A web page to remotely view the entire log of recoded exceptions. * A web page to remotely view the full details of any one logged exception. * In many cases, you can review the original yellow screen of death that ASP.NET generated for a given exception, even with customErrors mode turned off. * An e-mail notification of each error at the time it occurs. * An RSS feed of the last 15 errors from the log.

  • Comparing Checksums

    - by Sean Feldman
    This is something trivial, yet got me to think for a little. I had two checksums, one received from a client invoking a service, another one calculated once data sent into service is received. Checksums are plain arrays of bytes. I wanted to have comparison to be expressed as simple as possible. Quick google search brought me to a post that dealt with the same issue. But linq expression was too chatty and I think the solution was a bit muddy. So I looked a bit more into linq options presented in the post, and this is what ended up using: var matching = original_checksum.SequenceEqual(new_checksum); Sometimes things are so simple, we tend to overcomplicate them.

  • Numpad doesn't work after booting up - forced to reconnect USB keyboard after startup

    - by HorusKol
    I've tried this on two different USB keyboards - both of which work fine on a different computer running Windows XP. For some reason, the numerical keypad doesn't work probably immediately after booting up - neither the numbers work, nor the 'home' commands and so on that you can use with the numlock off. It doesn't make a difference whether I press numlock on or off - the keypad doesn't work correctly no matter what state this is in. However, once I've booted the machine I can disconnect/reconnect the USB connector for the keyboard, and it will work exactly as expected. I'm running Gnome on Ubuntu 10.04. The only other USB devices connected is a mouse - and I've experienced no problems with that. This is a direct connection to the box (not via an external USB hub)

  • Does anyone actually use the /// comment blocks?

    - by Rachel
    Someone once said we should prefix all our methods with the /// <summary> comment blocks (C#) and I am wondering if that is true or not. I started to use them and found they annoyed me quite a bit, so stopped using them except for libraries and static methods. They're bulky and I'm always forgetting to update them. Do you recommend using them? Why? EDIT: I normally use // comments all the time, it's just the /// <summary> blocks I was wondering about

  • Best Game Engine/Framework and Language for 2D actor/sprite intensive game

    - by Grungetastic
    I'm new to the game dev world. I have a rather large project in mind (I learn by setting myself challenges :P ) and I'm wondering what the best engine/framework/language is for a 2D game with thousands of sprites/actors on screen at a time. Bare metal type stuff. I need to still be able to zoom in and out with that many actors at once. This game will have no 3D elements. Any thoughts? Suggestions?

  • Detecting Duplicates Using Oracle Business Rules

    - by joeywong-Oracle
    Recently I was involved with a Business Process Management Proof of Concept (BPM PoC) where we wanted to show how customers could use Oracle Business Rules (OBR) to easily define some rules to detect certain conditions, such as duplicate account numbers, duplicate names, high transaction amounts, etc, in a set of transactions. Traditionally you would have to loop through the transactions and compare each transaction with each other to find matching conditions. This is not particularly nice as it relies on more traditional approaches (coding) and is not the most efficient way. OBR is a great place to house these types’ of rules as it allows users/developers to externalise the rules, in a simpler manner, externalising the rules from the message flows and allows users to change them when required. So I went ahead looking for some examples. After quite a bit of time spent Googling, I did not find much out in the blogosphere. In fact the best example was actually from...... wait for it...... Oracle Documentation! (http://docs.oracle.com/cd/E28271_01/user.1111/e10228/rules_start.htm#ASRUG228) However, if you followed the link there was not much explanation provided with the example. So the aim of this article is to provide a little more explanation to the example so that it can be better understood. Note: I won’t be covering the BPM parts in great detail. Use case: Payment instruction file is required to be processed. Before instruction file can be processed it needs to be approved by a business user. Before the approval process, it would be useful to run the payment instruction file through OBR to look for transactions of interest. The output of the OBR can then be used to flag the transactions for the approvers to investigate. Example BPM Process So let’s start defining the Business Rules Dictionary. For the input into our rules, we will be passing in an array of payments which contain some basic information for our demo purposes. Input to Business Rules And for our output we want to have an array of rule output messages. Note that the element I am using for the output is only for one rule message element and not an array. We will configure the Business Rules component later to return an array instead. Output from Business Rules Business Rule – Create Dictionary Fill in all the details and click OK. Open the Business Rules component and select Decision Functions from the side. Modify the Decision Function Configuration Select the decision function and click on the edit button (the pencil), don’t worry that JDeveloper indicates that there is an error with the decision function. Then click the Ouputs tab and make sure the checkbox under the List column is checked, this is to tell the Business Rules component that it should return an array of rule message elements. Updating the Decision Service Next we will define the actual rules. Click on Ruleset1 on the side and then the Create Rule in the IF/THEN Rule section. Creating new rule in ruleset Ok, this is where some detailed explanation is required. Remember that the input to this Business Rules dictionary is a list of payments, each of those payments were of the complex type PaymentType. Each of those payments in the Oracle Business Rules engine is treated as a fact in its working memory. Implemented rule So in the IF/THEN rule, the first task is to grab two PaymentType facts from the working memory and assign them to temporary variable names (payment1 and payment2 in our example). Matching facts Once we have them in the temporary variables, we can then start comparing them to each other. For our demonstration we want to find payments where the account numbers were the same but the account name was different. Suspicious payment instruction And to stop the rule from comparing the same facts to each other, over and over again, we have to include the last test. Stop rule from comparing endlessly And that’s it! No for loops, no need to keep track of what you have or have not compared, OBR handles all that for you because everything is done in its working memory. And once all the tests have been satisfied we need to assert a new fact for the output. Assert the output fact Save your Business Rules. Next step is to complete the data association in the BPM process. Pay extra care to use Copy List instead of the default Copy when doing data association at an array level. Input and output data association Deploy and test. Test data Rule matched Parting words: Ideally you would then use the output of the Business Rules component to then display/flag the transactions which triggered the rule so that the approver can investigate.

  • The Linux powered LAN Gaming House

    - by sachinghalot
    LAN parties offer the enjoyment of head to head gaming in a real-life social environment. In general, they are experiencing decline thanks to the convenience of Internet gaming, but Kenton Varda is a man who takes his LAN gaming very seriously. His LAN gaming house is a fascinating project, and best of all, Linux plays a part in making it all work.Varda has done his own write ups (short, long), so I'm only going to give an overview here. The setup is a large house with 12 gaming stations and a single server computer.The client computers themselves are rack mounted in a server room, and they are linked to the gaming stations on the floor above via extension cables (HDMI for video and audio and USB for mouse and keyboard). Each client computer, built into a 3U rack mount case, is a well specced gaming rig in its own right, sporting an Intel Core i5 processor, 4GB of RAM and an Nvidia GeForce 560 along with a 60GB SSD drive.Originally, the client computers ran Ubuntu Linux rather than Windows and the games executed under WINE, but Varda had to abandon this scheme. As he explains on his site:"Amazingly, a majority of games worked fine, although many had minor bugs (e.g. flickering mouse cursor, minor rendering artifacts, etc.). Some games, however, did not work, or had bad bugs that made them annoying to play."Subsequently, the gaming computers have been moved onto a more conventional gaming choice, Windows 7. It's a shame that WINE couldn't be made to work, but I can sympathize as it's rare to find modern games that work perfectly and at full native speed. Another problem with WINE is that it tends to suffer from regressions, which is hardly surprising when considering the difficulty of constantly improving the emulation of the Windows API. Varda points out that he preferred working with Linux clients as they were easier to modify and came with less licensing baggage.Linux still runs the server and all of the tools used are open source software. The hardware here is a Intel Xeon E3-1230 with 4GB of RAM. The storage hanging off this machine is a bit more complex than the clients. In addition to the 60GB SSD, it also has 2x1TB drives and a 240GB SDD.When the clients were running Linux, they booted over PXE using a toolchain that will be familiar to anyone who has setup Linux network booting. DHCP pointed the clients to the server which then supplied PXELINUX using TFTP. When booted, file access was accomplished through network block device (NBD). This is a very easy to use system that allows you to serve the contents of a file as a block device over the network. The client computer runs a user mode device driver and the device can be mounted within the file system using the mount command.One snag with offering file access via NBD is that it's difficult to impose any security restrictions on different areas of the file system as the server only sees a single file. The advantage is perfomance as the client operating system simply sees a block device, and besides, these security issues aren't relevant in this setup.Unfortunately, Windows 7 can't use NBD, so, Varda had to switch to iSCSI (which works in both server and client mode under Linux). His network cards are not compliant with this standard when doing a netboot, but fortunately, gPXE came to the rescue, and he boostraps it over PXE. gPXE is also available as an ISO image and is worth knowing about if you encounter an awkward machine that can't manage a network boot. It can also optionally boot from a HTTP server rather than the more traditional TFTP server.According to Varda, booting all 12 machines over the Gigabit Ethernet network is surprisingly fast, and once booted, the machines don't seem noticeably slower than if they were using local storage. Once loaded, most games attempt to load in as much data as possible, filling the RAM, and the the disk and network bandwidth required is small. It's worth noting that these are aspects of this project that might differ from some other thin client scenarios.At time of writing, it doesn't seem as though the local storage of the client machines is being utilized. Instead, the clients boot into Windows from an image on the server that contains the operating system and the games themselves. It uses the copy on write feature of LVM so that any writes from a client are added to a differencing image allocated to that client. As the administrator, Varda can log into the Linux server and authorize changes to the master image for updates etc.SummaryOverall, Varda estimates the total cost of the project at about $40,000, and of course, he needed a property that offered a large physical space in order to house the computers and the gaming workstations. Obviously, this project has stark differences to most thin client projects. The balance between storage, network usage, GPU power and security would not be typical of an office installation, for example. The only letdown is that WINE proved to be insufficiently compatible to run a wide variety of modern games, but that is, perhaps, asking too much of it, and hats off to Varda for trying to make it work.

    I want to make a site with different versions for 2 countries, which have the same language. Then I need to do the same for another language. Basically I want to have 6 versions of the site: UK English US English Default English ?? Austrian German Germany German Default German The question is, how do I define the "default" language versions, for any country with this language which isnt defined already? I know there is x-default, but I think you can only use that once and it is for all languages and all countries.

  • Should I ditch AJAX in client side web development when I've got a web-socket open?

    - by jt0dd
    I was thinking that maybe I should forget AJAX (HTTP) requests when I've got a web-socket open between client and server, but I decided I should ask here to check if this could be a bad practice for some reason that I'm not thinking of. Once the socket is open, there's less syntax (often meaning simpler error handling) involved in passing information between client and server with Socket.io (just one example of a web-socket). Is there some obvious situation where a web-socket (Socket.io for example) isn't going to be capable of handling a functionality that an AJAX request could do easily?

  • Corona SDK (Lua) vs Native Obj-C for iPhone only word puzzle type game [closed]

    - by dodgy_coder
    I am trying to decide on whether to use the Corona SDK & Lua versus native Objective-C to develop an iOS app. This will be the first game on any smartphone I have developed and so its not that ambitious - a single player word puzzle type game - something sort of like scrabble. The advantages of Corona I can see are: Lua is probably easier to learn than Obj-C (shorter learning curve) meaning a possibly quicker development time Possibility to port to Android once its finished Advantages of native Obj-C are: Access to all and latest features of iOS More / faster available libraries Has anyone made this decision before? Are there any major advantages or disadvantages I've missed or got wrong here? Thanks.

  • Do you have a plan for your digital assets after you die?

    - by pablo
    After reading this question I remembered of a news article about some websites that manage your online identity after you pass away. Have you planned what to do with your digital assets once you go? I'd imagine that your online footprint is as important as anything you leave of material value. I mean, what would be the difference of that open-source project that you created to the money and savings that you had? How would you like to have your identity managed after you pass away? Would you prefer to go "off the grid"? It's a sensitive topic and I never met anyone who prepared for it.

  • How many questions is it appropriate to ask as an intern?

    - by Casey Patton
    So, I just started an internship, and I'm worried that I'm asking too many questions. I've been assigned a mentor who has been assigning me projects and helping me learn all the company's technologies and methodologies. However, there's so much new material for me to learn while doing this project that I have a lot of questions. I generally ask questions over instant messages or E-mail (those are the primary modes of communication for my company). I'm trying to be careful not to ask too many questions: I don't want to come off as annoying or dumb. How many questions is appropriate to ask? Once an hour? More? Less? Keep in mind, my mentor is also a fellow programmer that has his own responsibilities.

Instead I see the bios post, the hard disk light flickers once and I have to install again (I have tried to re-install grub2). I am new to Linux and what I found that best answered my question was posted by James Henstridge. The instructions say to create disable-shutdown.pkla in etc/polkit-1/50-local.d/ but this directory does not exist, so do I create a folder titled 50-local.d in poolkit-1 or do I have to place this file elsewhere?

    I'm using Lubuntu 12.04. I can set my mouse (basic usb mouse) to left hand (i.e. switch the left and right mouse buttons which is all I need) by going into Preferences / Keyboard and Mouse. However, it changes my Wacom stylus, so that when the tip touches the tablet it acts like the right mouse button, making it impossible to draw. Is there a way to have both happen at once? The stylus buttons working in right handed configuration, while the mouse works in left handed configuration? Thanks for any help/suggestions.

  • How can I test if my rotated rectangle intersects a corner?

    - by Raven Dreamer
    I have a square, tile-based collision map. To check if one of my (square) entities is colliding, I get the vertices of the 4 corners, and test those 4 points against my collision map. If none of those points are intersecting, I know I'm good to move to the new position. I'd like to allow entities to rotate. I can still calculate the 4 corners of the square, but once you factor in rotation, those 4 corners alone don't seem to be enough information to determine if the entity is trying to move to a valid state. For example: In the picture below, black is unwalkable terrain, and red is the player's hitbox. The left scenario is allowed because the 4 corners of the red square are not in the black terrain. The right scenario would also be (incorrectly) allowed, because the player, cleverly turned at a 45* angle, has its corners in valid spaces, even if it is (quite literally) cutting the corner. How can I detect scenarios similar to the situation on the right?

  • How to discriminate commented code and documentation comments

    - by linquize
    After using version control tools, it is no longer necessary to comment out old code. However, some team members still comment out old code. Therefore, I want to clean them up. I want to mark commented lines which are really comments / documentation, so that every time I do not need to re-read all commented regions. The unmarked lines left are new commented code. How do I achieve this? Any existing tools or need to write on my own? Similar concept: in git, we have 'partial commit' to select some lines to commit. However, the lines marked in 'partial commit' is valid once only.
